The processing method of the surface of the CNC processing piece is first dependent on the technical requirements of the machining surface. However, it should be noted that these technical requirements for CNC precision machining are not necessarily the requirements specified in the partchart, and sometimes may be higher than the requirements of the part map due to process reasons.
There is a considerable range of machining accuracy and surface roughness available for any CNC processing method, but only in a narrow range is economical, this range of processing accuracy is economic processing accuracy. To this end, when the processing method is selected, the corresponding machining method can be obtained accordingly.
It is necessary to consider the nature of CNC processing materials.It is necessary to consider the structure shape and size of the CNC processing.
